How Much Is the Friction Acting on a Crate Sliding at Constant Velocity?

[pbody]

If you push on a crate with a force of 100 N and it slides at constant velocity, how much is the friction acting on the crate?

Consider a crate being pushed horizontally across a factory floor. If it moves at a steady speed in a straight - line path, it is in dynamic equilibrium. This tells us that more than one force acts on the crate. Another force exists likely the force of friction between the crate and the floor. The fact that the net force on the crate equals zero means that the force of fricition must equal and opposite to our pushing force.

What exactly is ur question??

U already got ur answer that friction force is 100N as there is no acceleration of crate and all
applied force is canceled by friction to keep body in dynamic equilibrium

My question was my answer I thought, but I was thinking if someone was pushing the crate at 100 N and there was 100 N of resistance how would they be pushing it but you answered my thought they wouldn't be.
